In Google Drive, I get a "The app is currently unreachable" page I try to download any non-document format (from what I can tell) such as PDF of GIF. TXT, DOC, and native Google Docs files seem to download just fine. The Reload/Stop and tab icon go bonkers and then I reach this page after a few seconds.

It happens whether I use the RMB menu or if I try to open the file and then click the big Download button when Docs says it can't open the file.

In addition to this issue, I sometimes get "Error 310 (net::ERR_TOO_MANY_REDIRECTS): There were too many redirects.".

Idea. Why don't you leave pepper flash off for WIndows also. Especially is you have it DISABLE. Because of automatically updates, you don't know that it gets turn back on till Flash video starts to be chubby.
